Application tiled April 4, 1888. Serial No. 269,637. (No model.)

To all whom it may concern:

Be it known that I, ELISHA MORGAN, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Paper-Cutting Machines, of which the following is a specification.

This invention relates to paper-cuttingmachines or presses' in which a heavy cutterboard is used, on which the paper is placed to beacted on by a cutter for cutting envelope-blanks and for other similar uses, the object being to improve the construction of the bed oi' the machine to the end that the inanipulation of said cutter-board may be tacili` tated and rendered less fatiguing to the operator, and that the paper-cuttin or waste may be removed from the bed of the machine by the movement of the cutter-board thereon, in order that they may not interferel with the operating device In the drawings forming part of this speci` ficat-ion, Figure l is a side elevation, partly in section, of a paper-cuttin g machine having my improvements applied thereto, the legs of the machine being shown broken oil'. Fig. 2 is a plan view of the bed and adjoining table ol the machine and of the cutter-board. Fig. 3 is a vertical section of a portion ot' the bed of the machine, in which are shown in side elevation and section one of the sp rin g-supported rolls and its supporting devices, all of which are hereinafter fully described. The parts of Fig. 2 shown in section are taken about on line Fig. l.

In the drawings, A indicates .a portion of the supporting-legs of the machine, on which the bed 2 thereof rests.

B indicates one of the upright parts of the frame of the machine above the bed thereof,

and 3 a transverse part of the frame extending between the upper ends ot' the said upright parts B. A driving-shaft on which is a balance-wheel, 4, has a `g-,eared' connection, as shown, with a crank-shaft, 5, which has a pitman-eonnection with a platen, G, as shown, whereby said platen is given a vertically-reciprocating motion over the bed 2. A table, 7, ordinarily of suitable wooden construction, is attached to one side el' thebed 2, as shown in Figs. 1 and 2, whose upper side is in the same plane as the bed 2.

In the employment of machines of this class for cutting envelope-blanks from a pile ot' through said pile ofv paper, a cutter-board, 8, i

is used of a considerable superficial area and of a thickness of three to four inches, which is made'from hard, and consequently heavy, wood, and is provided on one end with a han` dle, 9, and on the opposite end with a metallic strip, 10, which serves, more or less, to maintain the cutter-board in proper form and support it under the action oi' the above-described cutter when the latter is forced against its surta-ee. lhe said cuiter-boaul is of such considerable weight in itself, and especially when a thick pile of paper is laid thereon from which said blanks are to be eut, that when said cutter-board is allowed to rest with the whole of its under surface in Contact with the bed and the lia-ble of the machine the slid.- ing movement which is required to push the cutter-board and its load of paper under the platen (i demands such an expenditure ol; strength by the operator as makes it very fatiguiug and prevents ihe work lI'rom being done expcditimsly.

'lo obviate the above-referred-to inconvenience and provide supporting devices for the cutter-board and the paper thereon, whereby said beard temporarily supported above the plane of the bed and table of the machine while the bed is being moved to and fro between thc bed and the platen of the machine, rollers l2 are supported on suitable bearings within the bed 2 of the machine, whose peripheries normally project sli gh tl y above th e plane of the bed, as shown vin Figs. .l and 3, and similar rollers, 13, are hung in the table 7 el the machine, on which the cutter-board. moves and is supported. 'lhe said rollers l2, however, which are hung to rotate in the bed ol' the machine, are made capable of supporting the weight of the cutter-board and paper and the critter which is used while the latternamed parts are moved under the platen; but the bearings of said rollers are movable vertically, so that said rollers shall recede, leaving the cutter-board to bear directly against the upper side of the bed 2, when said platen moves downward against the cutter t) and forces the latter through the pile oi' paper and against the cutter-board, and when the platen rises said rollers follow its vertical movement and lift the cutter-board above the plane of the bed and support it while it is drawn oli from the latter, and thereby its movemen is made comparatively tree from any trictional resistance, sin ce it moves on said rollers. '.lhe said rollers 12, which bear the weight of the cutter-board and. the paper and cutter placed thcreuprm, have the journals thereof supported in boxes or beat-hugs 1l, whose lower ends are made ot cylindrical i'orm and tit into the upper ends oi.' hollow cylinders 15, which are supported vin avertical position on. a cross-bar, 11', secured to the under side olf the bed, shown in 'higx 1. '.lhe lower ends of said bearings 1i are somewhat reduced in diameter, as shown in Fig. 3, whereby a shoul der is formed thereon, against which the. upper end ot a spring, 17, bears, and the lower end ot said spring', as illustrated in Fig. il, bears on the upper enlarged end ot' a screwbolt, 18, havingl a screw engagement with said cross-bar 'lo'. The said springs 17, which sustain the weight ot' each roller 12 and a portion of that 'of the cut-tenboard and the thin supporti-ed thereby, are made of suitable resistance to sustain the weight oi said board, paper, and cutter, and they permit the abovereferred-to receding motion of the rollers when the platen 6 `is. forced against the Icutter C, and they litt `the rollers and the cutter-board when the platen moves upward, so that said board rests only on the rollers. li the machine is to be used in cutting blanks from a thickness ot" sheets of paper, 10, oi' substantially uuit'orm weight, said springs 17 may rest by their lower ends directly against said cross-bar 1o; but since the weight oi' paper which Ais placed on the cutter-board is variable, and without some means of adj listing,` said springs, whereby they are made capable of a variable resistance, they would not at all times properly supporti. and lift the cutterboa-rd away from the bed oil the i'nacl'iine, therefore the said screw-bolts 1S are provided, in order that said springs may be compressed or released, more or less, according' to the Weight which they have to sustain.

In cutting lblanks for envelopes or other similar articles from a pile ot sheets of paper, as above described, a mass of paper-cuttings produced, which falls more or less oft from the cutter-board onto the bed of the machine, and it' not `reguovcd they constitute an obstruction, by dropping into the roller-openings in said bed, to the tree rotary movement ot' the rollers when the cutter-board is moved over the bed, as described, and with the purpose of avoiding said inconvenience means are provided tor lnrushiug' said cuttings off from the bed of th-vp machine when the cutter-board is moved to and i'ro thereon, consisting` oi' a brush or a piece of felt, ai', which is secured in a pendingl position on one end oi' the cutterboard, as shown in Fig. 1, said brush lor felt extei'lding' across one end ot said board and having` the lower (alge thereot' in Contact with the surface oi' the bed when the eutter-board rests upon its carrying-rollers, is described, and thereby said telt or brush erniits the cutter-board to move toward and from the bed oi" the machine, as above described, without deranging said luushinp, device.

'.l`he above-rel'erred-to rollers` l 13 in the table 7 ot' the machine rotate in ixed bearings, as their function is only to support. the cutter-board while the paper itl and the cut.- tcr (l arel placed thereon and while the boa-rd is moved iroin the table onto the bed ot' the machine, as above described. 'lhe said cut'- ter-board-supportine rollers may consist et' one or more, each 'beingx oi' sutticit-.ait length to constitute a suitable support for the cutter-board, two or Fourbeing' preferable. Fig: 2 shows in full and in dotted lines four roll ers, the latter arrzimgement being advantageous when a very large eut-ter-lgioard is required.

That l claim as my invention 1. In a' paper-cuttinel machine, the combination, with ,the bed provided with vertically-moya ble j ournal-bearings, of rollers supported in said bearings, the cutter-board resting' and movable on said rolls, the reciprocating platen,and a cutter, sul'istantially as and t'or the purpose described..

In a paper-cutting machine, the combination, with the bed provided with verticallya'novable journal-bearings and sustaining-springs therefor, of rollers supported in said bearings, the cutter-board resting' and movable on said rolls, the. reciprotifatiu pl aten, anda cutter, substantially as and for the purpose described.

3. lu a paper-cuttiup,` machine, the combination, with the bed provided with vertically-movable journal #bearings sus'l'aining springs theret'or, and verticallyadjustable bearings for the lower ends of said springs, of rollers snl'ipmted in said bearings, the eutter-board resting` and movable on said rolls, the reciprocating platen, and a cutter, substantial ly as and tor the purpose described.

i. In combination, the bed l o't a papercutting-machine, one or more cutter-boardsustaining rollers hung to rotate in said bed, whose peripheries project normally above the plane thereof, a cutter-board capable of a reciprocating horizontal movement on said rollers, and a brushing,` device, substantially as described, attached to one end oi' said board, having' one end tl'iereoi' in contact with the surface ot said bed, substantially set forth.
